Verify that the CIP

radio-button is selected as the COMMUNICATION METHOD. The

PATH specifies the message route from the ControlLogix processor to the DFNT

module. Path elements are separated by commas. In the example path shown,

the first element is "Enet", which is the user-defined name given to the 1756-

ENET module in the chassis (you could substitute the slot number of the ENET

module for the name), the second element, "2", represents the Ethernet port on

the 1756-ENET module, and the last element of the path, "192.168.0.75", is the

IP address of the DFNT module, the target for the message.

More complex paths are possible if routing to other networks using multiple 1756-

ENET modules and racks. Refer to the Rockwell Automation Support

Knowledgebase for more information on Ethernet routing and path definitions.

Encapsulated PCCC Read Message

Read commands transfer data from the module to a ControlLogix processor. The

following encapsulated PCCC commands are supported from a ControlLogix

Processor:

 PLC2 Unprotected Read

 PLC5 Typed Read

 PLC5 Word Range Read

 PLC Typed Read

An example rung used to execute a read command is shown in the following

diagram:

The MESSAGE CONFIGURATION dialog box must be completed to define the data

set to transfer to the processor from the module. An example of the dialog box

follows:

1 2 ... 139 140 141 142 143 144 145 146 147 148 149 ... 176 177
